GAS-PRESSURE REGULATOR.

SPECIFICATION forming part of Letters Patent No. 271,735, dated February 6, 1853.

Application filed July 24, 1882. (No model.) Patented in Germany October 23, 1877. No; 2.471. and March 8, 187i). No. 6,798; in France August 23, 1878, No. 126,222, and in Belgium August 3l, 1878, No. 46,054.

To all whom it may concern Beit known that I, FRANZ PIPEasBnaG, of Liittringhausen, Prussia, in the Empire ot Germany, have invented certain new and useful Improvements in Gas-Pressure Regulators, of

which the following is a specitication.

` This invention has reference to an improved pneumatic gas-pressure regulator which works ina reliable and automatic manner and ad mits ro the, admission of the gas to the burners at a uniform pressure; and the vinvention consists ot' a gas-pressure regulator which is divided by a vertical central partition into two chambers, of which-one is connected with the gas I5 induction and eduction pipes, and provided at the interior with a chamber that is opened or closed by means of a valve arranged at the upper part, said valve being worked b v the rising and falling of an invertedbell-shaped 2o vessel, the space within which communicates with the valve-chamber by a U-shaped pipe. The chamber within which the regulating-vessel is arranged is filled with water or other liquid up to a certain level, the vessel and the lever-rod ot' the valve being applied to a crankshaft, to which is also applied, at the exterior end of the shaft, an adjustable weight for balancing the interior vessel and the gas-regulating valve.

In the accompanying drawings, Figure 1 represents a side elevation ot' my improved gas-pressure regulator. Fig. 2 is a horizontal section on line 2 2, Fig. l. Figs. 3 and 4 are respectively a vertical longitudinal section on line 3 3 of Fig. 2 and a vertical longitudinal section on line 4 4c of said gure. Fig. 5 is a vertical transverse section on line 5 5 of Fig. 2. Fig. 6 is a vertical transverse section on line 6 6 of Fig. 2. Fig. 7 is a top view of the 4o improved regulating-valve of my gas-pressure regulator on an enlarged scale; and Fig. 8 is a transverse section through said valve and the seat thereof.

Similar letters ot reference indicate corresponding parts.

The working parts of my improved gaspressure regulator are contained Within al square or oblongV box or casing, A, which is divided ,by a central longitudinal partition, A',

'eduction pipes b b'.

into twochamhers, B B', of which the chamber B is provided with the gas induction and l The second chamber, B', is filled with water orother suitable liquid, a bell shaped vessel, C, which is closed at the top and open at the bottom, being arranged p therein and connected by bracket-arms C' to a crank-shaft, (J2, the journals of which turn in bearings G3 of the side walls of the casing A and ofthe partition A', the shaft passingat one end through the side wallof the casing to the outside, at which point, land at the point ot' passing through the partition A', the bearings are hermetically sealed by mercury-vessels D. (Shown clearly in Fig. 2.) The hermetically-sealed bearings of one side wall of the casing A and ofthe partition A' are con nected by a transverse tube, D', (see Fig. 5,) which extends from one. bearing to the other below the crank-shaft C2.

To that part ot' the crank-shaft C2 which passes through the chamber B is applied a fixed arm, d, which connects by a forked connecting-rod, d', with a shde-valve, E, that moves over aperforated top plate or seat, E', of a third chamber, B3, which is formed by a transverse'partition, A2, that extends from the central partition, A', to the side wall of the casing A. The valve E maybe a common slide or other valve. I prefer, however, to'use a cylindrical valve which turns inthe bearings at the ends ot' the fork-shaped lever d',

Ato which and the top plate of the chamber 'B3 a piece of rubber, a, is applied, ot" sufficient dimensions to close the openings in the top plate when the roller is moved toward the shaft, as shown clearly in Figs. 5 and 6. When the roller moves in the opposite direction the sheet of rubber is wrapped around the roller, so as to open the gas-admission holes in the top of the chamber B3. The chamber B3 is connect- 9o ed by a U-shaped pipe, F, with the space above the liquid in the inverted vessel C, as shown in Fig. 4, said U-shaped pipe being ex'- tended by a plugged branch pipe, F', to the outside, so as to draw off any moisture which is collected in the U-shaped connecting-pipe F. g To the outer end of the crank-shaft (J2 is furthermore applied a fixed arm, e, from which extends a fixed lever, e', from which is suspended an adjustable weight, e2, which weight serves to balance the slide-valve E and theinverted vessel C, so as to render the latter more sensitive to the varying gas-pressures within the apparatus.

The operation of the regulator is as follows: The gas enters through the induction-pipe b into the chamber B, passes then through the perforations of the top plate of the chamber B3 to the interior of the latter, and through the U-shaped connecting-pipe F to the interior of the inverted vessel C. According to the higher or lower degree of pressure of the gas passing ont through the eduction-pipe b', the inverted vessel is raised or lowered, whereby, owing to the connection of the vessel by the crank-shaft C2 with the slide-valveE, the valveopenings are made smaller or larger, and thereby the supply of gas is diminished or augmented as required.

The size ot' the regulator has to be in proportion to the larger or smaller quantity of gas used per hour. I have found by a series of practical tests that when the area of the inverted vessel is equal to twenty-tive times the area of the cross-section ot' the inductionpipe a very exact and sensitive regulating action takes place.

The top of the casing A is provided with an opening,f, for supplying water. to the chamber B', as the quantity of water needs replenishing from time to time. It is also provided with an air-inlet opening,f, in the top part ot' the chamber B. The chamber B is furthermore provided with a plugged pipe, f2, in the end wall of the casing A, by which the height of the water-level in the chamber B is regulated.

My im proved gas-pressu re regulator is adapted for gasvfactories as well as for private use.

YVhen the regulator is of large size it is pref-V with inlet-openings communicating with the larger chamber, a. water-chamber adjoining the gas-chamber, an inverted vessel within said water-chamber, a U-shaped pipe connecting the smaller gas-chamber and the interior of the inverted vessel, a valve for partially closing the inlet-openings of the smaller gasehamber, and mechanism connecting said valve with the inverted vessel, whereby the latter actuates the former automatically in accordance with the pressure of the gas, substantially as set forth.

2. In a gas'pressure regulator, the combination of a gas-chamber provided with an induction-pipe, a smaller gas-chamber within the former, provided with an eduction-pipe and with inlet-openings communicating with the larger chamber, a water-chamber adjoining the gas-chambers, an inverted vessel within said water-chamber, a U-shaped pipe connecting the smaller gas-chamber and the interior ot' the inverted vessel, a double-crank shaft extending transversely through the adjoining gas and water chambers, arms rigidly connecting the inverted vessel with said crankshaft, and a valve adapted to partially close the inlet-openings otA the smaller gas-chamber, and connected by a rod with said crank-shaft, substantially as described.

3. In a gas-pressure regulator, the combination of thc partitioned casing A, having gascham bers B B3 and a water-chamber, B,a slidevalve, E, on the top ofthe gas-chamber B3, and an inverted vessel, C, arranged in the watercliamher B. the connecting-rods of the slidevalve and ofthe inverted vessel being attached to a double-crank shaft, (l2, and counterbalanced by an exterior weight, the journals of the crank-shaft C2 being inclosed in mercurysealed bearings D at the side wall and interlor partition, so as to prevent the passage of gas into the water-chamber and the leakage of water, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
